The weeks for which the team sold the same amount in percentages of candy bars are A. Weeks 1 and 2.

A percentage is a mathematical expression of the relationship between two numbers or variables.

It is also known as a ratio and is usually denoted as "%."

Week     Amount Sold

Week 1       32%

Week 2    eight twenty-fifths (8²⁰/₅₀)

Week 3 seventeen fifty-firsts (¹⁷/₅₁)

In percentage terms, the sales for each week are as follows:

Week 2    eight twenty-fifths (8²⁰/₅₀)

= 8²⁰/₅₀

= 160/500

= 32%

Week 3 seventeen fifty-firsts (¹⁷/₅₁)

= ¹⁷/₅₁

= 33%

Thus, the weeks for which the team sold the same amount in percentages of candy bars are A. Weeks 1 and 2.

The total number of coins that were in Kay's bank are 137 coins.

In order to determine the number of dimes and nickels, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Since she has 11 less dimes than nickels, an equation which models this situation is given by;

n = d + 11     ....equation 1.

Note: 1 nickel is equal to 0.05 dollar and 1 dime is equal to 0.1 dollar.

Additionally, the coins are worth 10 dollars;

0.1d + 0.05n = 10 ....equation 2.

By solving both equations simultaneously, we have:

0.1d + 0.05(d + 11) = 10

0.1d + 0.05d + 0.55 = 10

0.15d = 9.45

d = 63 dimes.

For nickels, we have:

n = d + 11

n = 63 + 11

n = 74

Now, we can determine the total number of coins;

Total number of coins = n + d

Total number of coins = 74 + 63

Total number of coins = 137 coins.

The equation of the line that passes through the points (1, 0) and (3, 6) is y = 3x - 3.

To find the equation of a line passing through two points, we can use the slope-intercept form of a linear equation: y = mx + b, where m is the slope of the line and b is the y-intercept.

Given points:

Point 1: (1, 0)

Point 2: (3, 6)

Step 1: Calculate the slope (m) using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates:

m = (6 - 0) / (3 - 1)

m = 6 / 2

m = 3

Step 2: Substitute one of the given points and the slope into the equation y = mx + b to find the y-intercept (b).

Using Point 1 (1, 0):

0 = 3(1) + b

0 = 3 + b

b = -3

Step 3: Write the equation of the line using the slope (m) and the y-intercept (b):

y = 3x - 3

Therefore, the equation of the line that passes through the points (1, 0) and (3, 6) is y = 3x - 3.

This equation represents a line with a slope of 3, indicating that for every increase of 1 unit in the x-coordinate, the y-coordinate increases by 3 units. The y-intercept of -3 means that the line crosses the y-axis at the point (0, -3). By substituting any x-value into the equation, we can determine the corresponding y-value on the line.

Hence, the equation of the line passing through (1, 0) and (3, 6) is y = 3x - 3.

We have a function,

\(f(x)=x^2-1\)

and we are asked to find its inverse function.

An inverse function essentially gets you the original value that was dropped into a function.

For example,

If I put 5 into \(f(x)\) I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.

The way to determine the inverse function swap the x and the \(f(x)\), then solve for \(f(x)\),

\(x=f(x)^2-1\)

\(f(x)^2=x+1\)

\(f(x)=\pm\sqrt{x+1}\)

Of course the notation demands that the obtained function be called,

\(f^{-1}(x)=\pm\sqrt{x+1}\)

Hope this helps :)

Answer:

The blue dot is -19

Step-by-step explanation:

Since every 2 ticks are worth 6 (|-10|-|-4|=6), then one tick is worth 3.

We are going backward, so we can count backward.

We have to go down 3 ticks, so -10-3=-13; -13-3=-16; -16-3=-19.

The blue dot is -19

Answer: The blue dot equals to -19.

Step-by-step explanation:

On the number line, there are the numbers -10 & -4.

-7 would fit in the middle of them. That means the number line goes by minus 3.

Count -10 , -13, -16, then you get on the the blue dot which is -19.

Therefore, -19 is the answer.

The formula used to calculate the variance of a set of data is Variance = \(s^2\)=1n−1n∑i=1(xi−¯x\()^2\).(Option-A)

To calculate the variance, each data point is subtracted from the mean, squared, and then added together. This gives the sum of the squared deviations from the mean. This sum is then divided by the total number of data points to get the average squared deviation from the mean, which is the variance.

Variance is a measure of the spread or variability of a set of data. It is useful in statistical analysis to understand how much the data points differ from the mean, and to compare different sets of data. Lower variance values indicate that the data is more tightly clustered around the mean, while higher variance values indicate that the data is more spread out.(option-A)

i got 4 because including the people that do swimming and park, the total number of people that do swimming is 22.

the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.

so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

Answer:

Step-by-step explanation:

First, you could factor 2 out of the whole thing.  The result would be 2(x^2-4x-45). Now we find the factors of 45 which are 1, 45, 5, 9, 15, 3. We have to find the pair that adds up to 4, and multiply to get 45. After some guess and check, we can find that 5 and 9 are those numbers. Now we have to get the right signs. Since the result is a negative number for -8k, and -90, the number that is a negative must be less than the other negative. -9<-5, so the answer would be 2(x-9)(x+5)

The Answer is: 20% . Chapter 1 Daily Value Practice Problems

The percentage of your daily value would equal 20%.

Given that, you need 2300 calories a day but you want to go on a lower carbohydrate eating plan. So you decide to get 40% of your calories from carbs.

Daily values are the recommended amounts of nutrients to consume or not to exceed each day and the DV% is how much a nutrient in a single serving of an individually packaged food or dietary supplement contributes to your daily diet. For example, if the DV for a certain nutrient is 300 micrograms and a packaged food or supplement has 30 mcg in one serving, the % DV for that nutrient in a serving of the product would be 10%.

According to the question, a person needs 2300 calories a day but because of this limited diet plan, he takes only 40% calories from carbohydrates.

Therefore, the calories needed for his diet=2300*40%

=2300*0.4

=920

The calories get by him after one serving of frosted mini wheat=48 gm of carbohydrates

1 gm of carbohydrates=4 calories

calories intake by him from carbohydrates=48*4

=192

% of his daily value=192/920*100

=0.208*100

=20.8=20%

Therefore, the percentage of your daily value would equal 20%.

The question gives us a figure of a 4-sided shape and we are asked to find what condition would make triangle HMG and GKH congruent.

We shall go through each option to know if they provide the necessary condition for both triangles to be congruent.

Option 1:

< HMK = < GKH.

If this is true then we have the following:

From the above, Therefore, The two triangles cannot be congruent using SAS.

Option 2:

The two angles, equal, it means that the figure formed must be a square. But from all indications, we only know that line MG = line HK.

Therefore, the two triangles cannot be congruent on this option.

Option 3:

MG || HK.

This option makes MH parallel to GH. Since MG = HK from the question, it implies that MH = GH as well. Meaning that

this condition makes the figure a rectangle.

And by the alternate angles theorem,

Hence, from triangle HMG and triangle GKH, we have:

line GM = HK, line GH is common and

La edad actual de José es de 30 años.

Para resolver este problema, primero debemos establecer ecuaciones basadas en la información proporcionada. Llamemos "x" a la edad actual de José y "y" a la edad actual de Ana. Según la primera condición, la edad de Ana es la mitad de la edad de José, por lo que podemos escribir la ecuación: y = (1/2)x.

La segunda condición nos dice que dentro de 10 años, sus edades serán dos tercios de sus edades actuales. Esto se puede expresar como: (x + 10) * (2/3) = y + 10.

Reemplazando el valor de y en la segunda ecuación con la primera ecuación, obtenemos: (x + 10) * (2/3) = (1/2)x + 10.

Resolviendo esta ecuación, podemos simplificarla y llegar a: 2(x + 10) = 3[(1/2)x + 10].
